I apologize in advance if this is listed in the INAT or another FAQ. If it is there, I didn't see it, hence the question.

What is the effect of psykout grenades on a GK squad. For instance, 1 GK squad equipped with psyk-out grenades assaults another GK squad. Are the results counted against the entire squad (reducing the entire unit to Init 1) or are the results resolved only against the Justicar / Knight of the Flame / random non-character model vis-a-vis the 'Brotherhood of Psykers' special rule?

Judging from some discussion on other forums, there still appears to be some confusion regarding this. I'd be thrilled to get a definitive ruling one way or the other.
